(Cl. 'l2-115) 3 Claims.

This invention relates to improvements in metal fabricated studding for partitions and the like Walls in buildings.

An object of the invention is to provide a metal fabricated adjustable studding of simple type and durable structure, and to which composite or metal lathing sheets or panels can be quickly and conveniently applied and securely clinched in place.

Another object is to provide a simple and efficient clip for binding together the meeting ends of a composite lathing board or panel for joints intermediate of the studding or unbacked.

Another object of the invention is to provide light weight metallic studs extensible to vary the effective length for economical construction of a fire-proof wall.

Another object is to provide metallic studs in their structure embodying spaced fastening elements extending therefrom for piercing and clinchingly securing sheet lathing to the studs.l

Various other objects and advantages of the invention will be more fully apparent from a description of the accompanying drawings, in which:

Referring to the drawings, each stud is composed of a, pair of duplicate sections I, 2, overlappingly joined or connected at one end to form an extensible unit for Varying the stud length to accommodate for irregularities Ain a Wall height and serve for different heights of Walls. The sectional form standardizes manufacture, as well as provides for extensibility, although the stud may be of a single unit for a definite wall height.

Each stud section in its fabrication comprises a pair of comparatively light gaugechannel bars 3, 3, of uniform length, and arranged in a determined spacing apart for a given width of stud. The bars at one end are permanently secured together by a tie plate or strut 4, preferably Welded to the outer side o-f the web portion of the channel bars, which, for the section, provides either a base or top plate for anchoring the stud t0 a base-or top rail 5, 5, represented as of channel form, which are rigidly secured to a support as floor and ceiling joists or other foundation by staples 6 or other fastening means most applicable for the type of support or foundation to Which the studs are applied. The end strut plate ll, preferably centrally of its Width and correspondingly of the stud, is notched to provide an opening to straddle the anchoring rail 5. The notching is of a character to form a pair of spaced flanges or lugs 1, 1, to obtain a more effective binding on the rail.

The bars, longitudinally, are additionally tied together to form a composite unitl by a plurality of cross rods 8 at determined spacings apart for a given length of stud section, and Welded or otherwise permanently xed to the bars. The cross rods are of a length to protrude beyond the relative opposite sides of the stud or stud bars to provide clinching extremities 9, 9, for piercing through the composite or metallic lathing in applying the same to the studding in forming a plastering or coating under-support for the Wall.

As shown, the plaster under-support comprises a commercial composite board l0 of a selected square foot area, and is generally referred to as a plaster board, consisting of a slab of gypsum 0r the like material enclosed by a paper binding or envelope adhesively bonded thereto. In erecting the plaster board or sheet lathing, it is desired to have the opposite ends extend slightly beyond the studding, so that the protruding fastener elements 9 pierce through a solid portion of the sheet lathing for a more rm securance to the studding. The lathing sheet may be either pre-punched or may be pressed over the fastener extremities of the stud, Whichever is preferable to the erector, after which, the

protruding end of the fastener is bent over to an angle and clinched upon the face side of the lathing sheet.

With the stud for a Wall height composed of a pair of sections of duplicate structure, the sections are lapped together at one end, providing for extensibility of the stud to meet irregular or varying conditions of height, usually encountered in the erection of partition walls or for rendering the stud extensible for different wall heights, with the lapping of the sections intermediate of the ultimate wall height to reinforce the same centrally of its length. The strut extending extremities of the cross bar or tie rods are also employed for securing the lapped sections together, eliminating the use of extraneous means therefor, and also serving to more securely bind the sections together.

The ends of the tie or strut rods, being ductile, can be readily clinched over, and the spacing is arranged to accommodate for certain sizes of lathing sheet so that the clinching is intermediate of its end edges. The studdings are arranged at selected spacing apart, according to the sheet size of lathing employed, so that the edges of the lathing bring the joint of two adjoining sheets between the studding, at which they can be conveniently tied together by a spring clip of a preferred type as illustrated in Figure 8.

The clip preferably is formed of wire, bent to provide a pair of reverse bend limbs II, I I, combined by a central cross bar portion I2, which is adapted to be compressively slipped over the opposing or joint edges of a pair of adjacent lathing sheets, with the cross bar portion I2 of the clip lying in and traversing the joint space to dispose the reverse bent limbs respectively at relative opposite sides of the lathing sheets, and `overlap the margins thereof. Any selected number of clips may be used to obtain the desired rigidity for the joint and overcome any objectionable yield. The clips are frictionally held in place under a suiicient clamping pressure, so as not to be disturbed or interfere in the application of a plastic layer or coating over the lathing sheets.

In Figures 9 to 14 inclusive, a modified form of combined stud plate and clip is illustrated, which increases the rigidity of the stud, and provides for a mechanical method of securing the struts to the verticals or stud bars. In such instance, the struts I3 are formed of strip metal, press punched, each at its opposite ends to provide a longitudinally projecting tang Ill. The strut is secured to the stud bar by punching a pair of lips I5, I5, centrally out of the web portion of the bar, and clinching each over and upon the strut and through a notch I6 in the edge of the strut.

This method also lends itself admirably in producing a metallic furring stud I'I as shown in Figures andy 16, usually applied and secured to a solid wall to effect a spacing between the solid and covering walls. For such purpose, the furring stud constitutes a single channel bar provided with a series of determinately spaced tangs I8 extending therefrom for securing the sheet lathing. The tang is xed to the bar in a manner similar as explained for the stud strut connecting a pair of stud bars.

Having described my invention, I claim:

A building stud, comprising: a pair of duplicate stud sections, each composed of a pair of channels in spaced relation with their webs extending in a common plane, a metallic plate secured to one end of the channels of the stud section to provide a channel connecting cleat intermediately notched, the notch open to the outer edge for engagement with an anchoring rail extending longitudinally of a wall for securing the cleated end of a stud section against lateral displacement, cross struts fixed to the channels in relatively spaced relation longitudinally of the channels with their opposite ends extending beyond the width of the stud section providing bendable fastener elements for fixing wall panels to the stud, the pair of stud sections overlappingly secured together at one end by one or more of said cross struts extensively uniting said sections to produce an effective stud length with the cleated ends of the stud sections respectively at relative opposite ends of the stud.
